Unusual Location of Primary Hydatid Cyst: Soft Tissue Mass in the Parapharyngeal Region

Hydatid cyst is a cyclozoonotic infection caused by the cestode Echinococcus granulosus . Hydatid cyst in the head and neck region is very rare, even in countries where echinococcus infestation is endemic. We report the case of a 17-year-old male patient presenting with a hydatid cyst in the parapharyngeal and neck region. There was no pulmonary or hepatic involvement. The definitive therapy comprised excision of the cystic mass and postoperative medical treatment.
